二、使用mysql-jdbc连接MySQL出现如下警告：Establishing SSL connection without server's identityverification

1.Java使用mysql-jdbc连接MySQL出现如下警告：

Establishing SSL connection without server’s identityverification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+requirements SSL connection must be established by default if explicit optionisn’t set. For compliance with existing applications not using SSL theverifyServerCertificate property is set to ‘false’. You need either toexplicitly disable SSL by setting useSSL=false, or set useSSL=true and providetruststore for server certificate verification.
